5 Elements of Efficiency

Design, Heat recovery, Control, Centralization, Competence – these five elements determine the efficiency of each vacuum process. Optimizing these elements and how they interact will lead to the best solution.

Keeping an Eye on All Elements:

A Holistic Approach to Vacuum Efficiency

Optimizing the efficiency of vacuum applications can bring significant cost savings. It is worth analyzing vacuum generation in all its complexity.

Selection of the right vacuum pumps and all components for a vacuum application is important, but it is not the only factor determining efficiency. Even the best technology cannot achieve its true potential if it does not interact perfectly with the process. Sizing to process requirements is the key. Any selection of vacuum components should therefore always be driven by individual process requirements rather than by simply comparing the performance data of individual components.


There is no such thing as an efficient plug and play solution in vacuum processes without first considering all process conditions. Furthermore, state-of-the-art technology operating at the highest level of energy efficiency can never deliver its full potential if it is not tailored to the process. Achieving optimum process output, process stability and high availability, as well as the highest possible level of economic efficiency, requires the thorough consideration of all elements.

The Busch 5E concept takes into account all of these elements. 5E stands for the five key elements that determine the efficiency of vacuum processes: Design, Heat Recovery, Control, Centralization and Competence.

Efficiency by Design

Leading in Performance and Efficiency Through Continuous Improvement

The design and quality of vacuum pumps are crucial to performance, efficiency and total life cycle costs.

There are many ways to generate vacuum. But often only one operating principle delivers the greatest possible efficiency for a specific application. The configuration of the selected principle is then the key to the efficiency factor. Efficient vacuum supply starts with the design of the core component – the vacuum pump. The way in which vacuum is generated, the design of flow paths, temperature distribution, the spatial ratio of compression chambers inside the vacuum pump – all of these factors play a decisive role.

Our global research and development teams are constantly working to optimize proven technologies and develop new products to make vacuum generation even more efficient and to offer an extensive product portfolio. Experience from thousands of installations worldwide and the close cooperation with the customers flow directly into the development and improvement of Busch vacuum pumps.


Efficiency by Heat Recovery

Efficiency Through Optimum Use of Exhaust Heat

During operation, vacuum pumps convert kinetic energy into heat energy. Heat recovery systems can harness this energy.

Even the most efficient vacuum pumps generate heat during operation, which is usually released into the environment. Instead of wasting this energy by simply removing the exhaust heat, the consumed energy can to a large extent be recovered for reuse in other areas of the company. For example to generate hot water or to heat spaces or buildings. As a general rule, on average 50 to 70% of the motor's energy consumption can be recovered.

Apart from being wasted, the heat energy emitted by vacuum pumps has a strong impact on the ambient temperature of the production area. In air-conditioned rooms, this heat has to be offset by the air conditioning system, which leads to a higher energy consumption and consequently to higher energy costs.

Thus, the use of heat exchangers in vacuum generation processes allows the reduction of the overall energy consumption as well as CO2 emissions and therefore has a positive impact not only on the environment but also on energy costs.


Efficiency by Control

Intelligent Vacuum Control Systems for Efficient Operation

Control of vacuum systems perfectly tuned to production ensures optimum process stability and output.

Each vacuum application has its own specific characteristics. Vacuum demand often varies within production processes. Ideally, the vacuum supply should be synchronized with demand, which saves operating costs. Simply switching vacuum pumps on and off according to the production cycle is not a feasible solution. The reason is because operating vacuum pumps at their point of maximum efficiency and meeting the vacuum demand of the production cycle are two very different things. Saving on one side of the equation can lead to a loss on the other. A control system is the solution, balancing process efficiency and vacuum efficiency.


Efficiency by Centralization

The Centralized Approach to Maximum Efficiency

A central vacuum supply offers the potential to reduce operating costs and to increase energy efficiency.

Where many individual vacuum pumps are used, the centralization of vacuum supply will offer advantages in terms of efficiency, process stability and availability. A single vacuum pump installed directly at the point of use is always operating when the process is running, even if the demand for vacuum is low or non-existent. In contrast, in a centralized vacuum system, the workload is distributed across several vacuum pumps.


Efficiency by Competence

Experience Bringing Efficiency to Your Processes

Efficient operation of vacuum processes requires experience in the interaction of all process components.

Vacuum pumps and systems are the key components in many production processes. Availability, reliability and efficient operation are therefore factors that must be evaluated in any approach to increasing efficiency and thus reducing cost of operation. An efficient vacuum supply can only be guaranteed by understanding the interaction of every single process component. Busch draws on more than 50 years of experience in the design, production and operation of vacuum pumps and systems. Specialized Busch engineers in all parts of the world assist our customers by analyzing their specific process requirements and suggesting a solution that takes into account all factors. This guarantees the highest level of efficiency in vacuum generation.
